Description
Автор предлагает применить дл усилени слабых токов схему, состо щую из катодных усилительных ламп. Согласно прилагаемой схеме, дополнительный усилитель состоит из трех катодных ламп, работающих на повышенном напр жении и накале, при чем усил емое напр жение подводитс через трансформаторы к сеткам двух ламп 2 и 3, из которых лампа 2 присоединена анодною цепью между анодом и сеткой , а втора 3-между сеткой и нитью третьей лампы 7; в анодный контур последней лампы включен прибор, регистрирующий усиленный ток. Кажда из ламп питаетс отдельной батареей накала, и сетки управл ющих ламп соединены с минусом накала при помощи вторичных обмоток трансформаторов . Первичные обмотки трансфорjf маторов соединены последовательно, так что вход щий ток действует одновременно на обе лампы. Устройство дл усилени токов посредством катодной лампы, характеризующеес тем, что между анодом и сеткой катодной лампы 7, дающей ток дл использовани , подключена усилительна лампа 2, а между сеткой и нитью той же лампы 7 подключена усилительна лампа 3, при чем усиливаемый ток подводитс к первичным обмоткам трансформаторов Т и Т, вторичные обмотки которых подключены одним концом к сеткам ламп 2 и 5. ПРЕДМЕТ ИЗОБРЕТЕНИЯ.The author proposes to use a circuit consisting of cathode amplifying lamps for amplifying weak currents. According to the attached diagram, an additional amplifier consists of three cathode lamps operating at an overvoltage and an incandescent voltage, the amplified voltage being supplied through transformers to the grids of two lamps 2 and 3, of which lamp 2 is connected by an anode circuit between the anode and the grid, the second 3-between the grid and the thread of the third lamp 7; In the anode circuit of the last lamp is included a device that registers the amplified current. Each of the lamps is powered by a separate battery, and the grids of control lamps are connected to the minus of the heat by means of the secondary windings of the transformers. The primary windings of the transformer mafors are connected in series, so that the incoming current acts simultaneously on both lamps. A device for amplifying currents by means of a cathode lamp, characterized in that an amplifier lamp 2 is connected between the anode and the grid of the cathode lamp 7, which gives current for use, and an amplifier lamp 3 is connected between the grid and the filament of the same lamp 7. the primary windings of the transformers T and T, the secondary windings of which are connected at one end to the grids of the lamps 2 and 5. SUMMARY OF THE INVENTION.
